That's cute. Also just reading the first part "Drone captures narwhals using their tusks..." my mind jumped to a more sinister interpretation, poachers using drones to spot and hunt narwhals by recognizing tusks with AI... I've clearly been reading too many AI headlines recently.
'The tusk, especially the tip of the tusk, was used to interrogate and manipulate the target by brief contact, which typically elicited a response from the fish.'
Well, yes, if you were poked by one of those tusks you'd react!
In Vienna you can see a narwhal tusk that was sold to the emperor as a unicorn’s horn. I’d love to know the story - probably a dead narwhal washed up in a beach, someone took the horn, then how many hands it passed through before making it to the Austrian empire, and who actually believed it was from a unicorn?
